Tour of prototypes and discontinued products

I've added a section to the site, with information, descriptions, and photos of all the old versions and prototypes of the Sentry Shield and Standalone Sentry Controller. Some of you might find this useful, if you bought one of these older versions and are looking for copies of the design files / instructions for them. Others might just find it an interesting tour of the history of Project Sentry Gun. Either way, the list can be found at http://psg.rudolphlabs.com/products/discontinued.
